Abstract: A process is disclosed for using the existing Universal Resource Identifier (URI) history feature of browsers to maintain user preference settings, or other state information, used by one or more web sites or other systems. In one embodiment, when a user makes a particular preference selection on a web site, the user's selection is recorded in the browser's URI history by causing the browser to access a URI (or a set of URIs) representing the particular selection. The same or a different web site may subsequently test the browser's URI history for this particular URI by including appropriate JavaScript or other executable code in a page requested by the browser. Depending upon the outcome of this test, the web site and/or the page's executable code may take an appropriate action or inaction consistent with the preference selection.

Abstract: A signal mapping system maps sensor signals into control signals that control the operation of a music synthesizer. A "one to many" mapping technique is used, allowing at least some of the sensor signals to each be mapped into numerous music synthesizer control signals. Physical gestures by a user are mapped into a large set of music synthesizer control signals, some of which continuously vary in value as the user moves through the gestures. Signal mapping functions are used to map the sensor signals into note number and velocity values for at least one voice to be generated by the music synthesizer. The note number and velocity values are sent to the music synthesizer as note-on events when predefined note-on and note-off trigger conditions, defined with respect to specified ones of the sensor signals, are satisfied. Other ones of the signal mapping functions are used to generate asynchronous control signals that are sent to the music synthesizer independent of the note-on and note-off events.
